Fax detecting after Dahdi upgrade to 2.2.0.2-1

Hi all.
I’ve updraded mu freepbx to 2.5.1.0 version.
I’ve a TDM400 card

[[email protected] asterisk]# dahdi_hardware

pci:0000:01:01.0 wctdm+ e159:0001 Wildcard TDM400P REV I

[[email protected] asterisk]# dahdi_scan

After a yum update of dahadi drivers now the system cannot recognize fax ;(
During an incoming call i’ve this message:

– Redirecting DAHDI/3-1 to fax extension
– Sent into invalid extension ‘�’ in context ‘ivr-3’ on DAHDI/3-1
– Executing [[email protected]:1] Set(“DAHDI/3-1”, “MSG=it/ufficio/errore_tasto_incorretto”) in new stack
– Executing [[email protected]:2] Goto(“DAHDI/3-1”, “loop|1”) in new stack

Can someone help me?
Thans in advance.
Vito.
